  Therefore, the present invention relates to the line indicator disclosed in Patent Document 2, in which the engaging claw of the joining member can be easily detached from the engaging portion of the engaging member, and the inner surface of the surface plate of the engaging member. Provided is a line marker that can prevent damage to an engaging portion by clearly indicating the presence of the engaging portion when a joint portion is provided.

According to a first aspect of the present invention, there is provided a line sign body having a pair of engaging members having the same shape in which a front plate and a rear plate are arranged to face each other at a required interval via a U-shaped bent portion, and a steel tower. On the surface plate of both engaging members that are mounted with the surface plate facing the outer surface from the end surfaces of both sides of the angle, in the expanding direction on the folded top portions of both covering plates that extend from the corner to the tower angle It is composed of a sharp angle mountain-shaped joining member provided with a resisting elastic force urging portion, and the engaging member is formed by striking multi-stage inclined guide surfaces parallel to the longitudinal direction at both ends in the longitudinal direction of the surface plate. A joint portion is disposed, and a required number of protrusions are provided on the back plate so as to protrude toward the outer surface, and at the lower end portions of the both cover plates of the joining member, a portion corresponding to the engaging portion of the engaging member is provided. In the line marking body formed by disposing the engaging claws bent upward at an acute angle toward the inner surface,
Inclined guide surfaces of the engaging portion are arranged in two rows, a tool insertion opening is opened in the middle, and an engaging claw of the joining member is formed in a bifurcated engaging claw , and a tool insertion opening is formed in the middle Is arranged.
The circuit marker described in claim 2 is the circuit marker described in claim 1,
At both ends perpendicular to the longitudinal direction of the covered plate of the joining member, a slit projecting portion of the height and width of embryonated said engaging portion is Tate設, at the top surface lower end of the convex portion, provided at both ends The bifurcated engagement claw is disposed on an independent deformable tongue piece formed between them, and a tool insertion opening is opened between both engagement claws .
The circuit marker described in claim 3 is the circuit marker described in claim 1,
A tool insertion opening in the joining member is provided between the engaging claws formed at the lower end of the joining member and is provided on a convex portion that is erected upward perpendicular to the longitudinal direction of the two covering plates.

At both ends in the longitudinal direction of the engaging member, the multi-stage inclined guide surfaces forming the engaging portion are arranged in two rows, a tool insertion opening is opened in the middle, and the forked shape is engaged with the inclined guide surfaces of each row Since the tool insertion port is disposed in the same phase as the tool insertion port between the engagement claws of the steel plate, the joint is simply engaged with the engagement member by pressing the joining member corresponding to the length of each side of the tower angle. it can. When separating and detaching the two, the engaging claw can be easily removed from the engaging portion by inserting a tool such as a screwdriver toward both the tool insertion openings and raising the tool upward. When two rows of inclined guide surfaces are formed on the inner surface side of the surface plate of the engaging member, a tool such as a screwdriver is inserted into the tool insertion opening disposed between the two inclined guide surfaces and the surface plate is pressed down. After that, if a tool such as a screwdriver is inserted into the tool insertion port of the convex portion standing on the joining member and placed on the upper surface side, the engaging claw can be easily removed. Even if during maintenance and inspection work to move on the tower angle, without its vicinity power it is crushed since the convex portion is visually inclined guide surface is securely provided on the inner outer surface of the surface plate of the fastening member In addition to being maintained, the feet are not slid and the safety of the maintenance inspection work is ensured.

The U-shaped bent portion of the engaging member has a size sufficient to insert the side of the tower angle whose inner diameter is the object, or the height of the engaging portion (when the engaging portion is formed on the inner surface of the surface plate) ), So that a narrowed portion can be formed between the front plate and the back plate so that it can be firmly engaged with a thin side, and the engagement portion and In this method, the inclined guide surfaces are punched in multiple steps on the outer surface of the face plate, the middle is cut and divided to open the tool insertion slot, and the two rows of inclined guide surfaces are punched in multiple stages, inevitably with the tool insertion slot in between. Such as an opening. In other words, when two rows of inclined guide surfaces are launched in multiple stages , and each individual inclined guide surface is provided in multiple stages on the outer surface of the surface plate, the lower surface of the tool insertion slot (the upper surface of the surface plate) forms a flat guide surface. It becomes easy to insert a tool.
In addition, when forming the engaging portion on the inner surface of the surface plate of the engaging member, it is more effective to form a tool insertion port by punching out a series of inclined guide surfaces in a multistage manner and cutting and cutting the middle between them. When each engagement claw is disengaged from each inclined guide surface, a tool such as a screwdriver can be inserted into the tool insertion port through the punched hole from the upper surface of the surface plate, and the surface plate can be pressed. Even if the convex portion is raised with a tool inserted into the tool insertion opening, the engagement claw is not lifted and lifted together with the surface plate when the engagement claw is released.
Further, with respect to an engaging portion in which two rows of inclined guide surfaces are arranged in multiple stages on the outer surface of the surface plate of the engaging member, each engaging claw that engages with the inclined guide surface of the engaging portion is a joining member. The protrusions are easily fitted and positioned so that they can be easily engaged. However, if two rows of inclined guide surfaces are arranged in multiple stages toward the inner surface of the surface plate of the engaging member, The left and right outer ends of both engaging claws disposed at the inner end of the guide surface at the side of the punched hole and the lower end of the joining member (the left engaging pawl and the right engaging pawl) The right end) is the positioning end, so that the engagement portion is formed by enlarging the width dimension of both inclined guide surfaces with respect to the width dimension of both engagement claws in view of the engagement displacement in the left-right direction. In this case, the punched end along the longitudinal direction of the inclined guide surface in the surface plate corresponds to the engagement of the engaging claws of the joining member.

  The present invention will be described with reference to an embodiment. As shown in FIG. 1, the line marker A is composed of a pair of engaging members 5 having the same shape and an acute angle mountain-shaped joining member 9 made of a stainless steel plate. The engaging member 5 has a tall surface plate 2 and a lower back plate 3 opposed to each other at a required interval via a bent portion 1 bent in a U-shape, and the facing interval is partially set. A pair of members having a required length with a narrowed throttle portion 4 is prepared, and one of the engaging members 5 is used in a symmetrical state with its length direction reversed. As shown in FIG. 2, the joining member 9 is made of a stainless steel plate, is laid over the surface plate 2 of the two engaging members 5 that are externally fitted to the sides 18 of the tower angle 17, and is bent into an acute angle mountain shape. Further, a resilient force biasing portion 8 is provided in the folded top portion 7 of both the covering plates 6. Further, the engaging member 5 is inclined at a required height of a required width descending toward the bent portion 1 perpendicular to the longitudinal direction at both ends of the outer surface longitudinal direction of the surface plate 2 as shown in FIGS. The guide surfaces 10 are driven in multiple rows in two rows to the outer surface, the engaging portion 11 having a tool insertion port 19 opened between the inclined guide surfaces 10 and 10 is disposed, and the back plate 3 has a conical shape for preventing slippage. The protrusion 12 protrudes toward the outer surface. And both the covering plates 6 of the joining member 9 are vertically provided with convex portions 13 having a height and a width for embedding the engaging portions 11 at portions corresponding to the engaging portions 11 of the engaging members 5. As shown in FIG. 8, at the lower end of 13, small slits 14 are arranged on both side edges of the top surface in the width direction from the lower end to the bent top 7, and the independent slit formed between both slits 14, 14 is provided. The deforming tongue 15 is provided with a bifurcated engagement claw 16 that is bent at an acute angle from its lower end toward the inner surface of the covering plate 6 and whose width is narrower than the width of the inclined guide surface 10. As shown in FIG. 6, a tool insertion opening 19a into which a tool such as a screwdriver can be inserted is opened between the engaging claws 16 and 16.

As shown in FIG. 2, the line marker A constructed in this way has the engaging members 5 fitted to the sides 18 of the tower angle 17 with the surface plate 2 facing the outer surface. The covering plate 6 is straddled on the surface plate 2 of the engaging members 5. At that time, when the elastic force urging portion 8 of the bent top portion 7 formed in an acute angle mountain shape is pushed in, both the covering plates 6 are formed at an angle against the elastic force of the elastic force urging portion 8. While being expanded, each engaging claw 16 is guided by each inclined guide surface 10 of the engaging portion 11 of the engaging member 5 along with the elastic deformation of the independent deformable tongue 15 in the vertical direction on the surface plate 2. Finally, the bending top portion 7 of the joining member 9 is pushed to a position close to the top portion (corner portion) of the tower angle 17, and when the pressing force is released at this point, the elastic force biasing portion 8 The joining member 9 is slightly lifted on the both surface plates 2 by the tightening force, but at that time, the independent deformable tongue 15 is deformed along the inclined guide surfaces 10 by the elastic force. The line marker A is attached to the tower angle 17 by meshing with the lower end of each inclined guide surface 10 of the engaging portion 11. It is.
As shown in FIG. 7, when each inclined guide surface 10 is driven out toward the inner surface of the surface plate 2 of the engaging member 5, each engaging claw 16 of the joining member 9 that meshes with the inclined guide surface 10. Since the outer end in the left-right direction is positioned at the inner side end of the punched hole of the inclined guide surface 10, both inclined guide surfaces 10 with respect to the width dimension of the two engaging claws 16 are anticipated. And the tool insertion port 19a is convex upward between the two engaging claws 16, 16 formed at the lower end of the joining member 9. The convex part 21 which formed in the inside is standingly arranged toward the bending top part 7 from a lower end. In this case as well, the joining member 9 is pushed into the engaging members 5 and the bifurcated engaging claws 16 disposed at the lower ends of the engaging claws 16 are engaged with the outer surfaces of the inclined guide surfaces 10 in contact with each other. Although it is slid down on the joint portion 11, when the pressing force is released in a state of being properly attached to the tower angle 17, the joining member 9 is slightly lifted, and by the elastic restoring force of the covering plate 6 including each engaging claw 16. Each engaging claw 16 is lowered toward the inner surface of the surface plate 2, and as a result, as shown in FIG. 5, each engaging claw 16 is engaged with a punched end along the longitudinal direction of each inclined guide surface 10.
As described above, when the inclined guide surface 10 is formed on the inner surface side of the surface plate 2 and the engaging claw 16 of the joining member 9 is engaged with the punched end, it is engaged with the surface of each side 18 of the tower angle 17. Although a space corresponding to the launch height of the inclined guide surface 10 is generated between the back surfaces of the surface plate 2 of the member 5, the convex portion 21 is erected between the both engaging claws 16, 16 of the joining member 9. 21 is visually observed and the both inclined guide surfaces 10 are not crushed and are maintained safely.
In order to disengage both the engaging claws 16 of the joining member 9 from the both inclined guide surfaces 10 of the engaging member 5, when both inclined guide surfaces 10 are disposed on the outer surface of the surface plate 2, FIG. As shown, the tool insertion port 19 opened between the two inclined guide surfaces 10 and 10 and the tool insertion port 19a opened between the engagement claws 16 and 16 communicate with each other. If a tool such as a screwdriver is inserted into 19a, both engaging claws 16 are easily detached from both inclined guide surfaces 10. As shown in FIG. 7, when both inclined guide surfaces 10 are arranged on the inner surface of the surface plate 2, a convex portion 21 in which a tool insertion opening 19 a is formed between both engaging claws 16, 16 of the joining member 9. Therefore , a tool such as a screwdriver is inserted into the tool insertion port 19a of the convex portion 21, and the other is directed from the upper surface of the surface plate 2 toward the tool insertion port 19 opened between the two inclined guide surfaces 10 and 10. If the tool is inserted and the top plate 2 is pressed and the tool insertion port 19a is moved upward with a tool, both the engaging claws 16 are easily detached from the punched ends on the both inclined guide surfaces 10.

  As shown in FIG. 4, the circuit sign A having the above-described configuration is attached to the tower angle 17 of the power transmission tower 20 as appropriate, for example, with the right side of the power transmission tower 20 being yellow and the left side being red for each electric circuit.

  The present invention greatly contributes to the power-related industry in terms of the maintenance and management of high-voltage power transmission lines in terms of simplification of installation and removal work on the tower angle and improvement of safety, and improvement of productivity due to mass production with a simple structure. it can.
